Anleitung Zusammenfassung
The antenna splitter incorporates DC distribution for powering up to four receivers in addition to two antenna boosters via a single mains unit. By linking two ASP 2 antenna splitters, an 8-channel system can be operated with only two antennas. By using the GA 2 rack adapter, two antenna splitters or one antenna splitter and one rack-mount receiver (e.g. EM 100 G2, EM 300 G2 or EM 500 G2) can be mounted into a 19" rack. Areas of application: • Small to medium RF installations (fixed or mobile) • Permanent installations in small theaters, conference centers and similar venues Delivery includes • 1 ASP 2 antenna splitter • 1 set of plastic feet • Instructions for use Safety instructions Caution! Never open the unit! If units are opened by you in breach of this instruction, the warranty becomes null and void. Attention! Make sure that the air vents of the unit are not covered or blocked! Keep the unit away from central heating radiators and electric heaters! Caution! Set up the unit on an even surface or mount it into a rack! Lay the cables in such a way that no-one can stumble over them! Attention! Keep liquids and small parts which conduct electricity away from the unit! Use a slightly damp cloth for cleaning the unit. Do not use any solvents or cleansing agents! 16 Operating controls DC input (DC IN) for mains unit Cable grip for power supply DC cable Four DC outputs (DC OUT) for powering up to four receivers Antenna input B (IN B, DC-FEED 12 V), BNC socket Four antenna outputs (OUT B), B leg Four antenna outputs (OUT A), A leg RF output A (link to antenna input B to make a 1-to-8 splitter), BNC socket Antenna input A (IN A, DC-FEED 12 V), BNC socket Putting the unit into operation The below connection diagram shows the connections for a 4-channel diversity system. Setting up the unit The unit is suitable for use as table top or can be mounted into a rack. . For mounting the unit into a 19" rack, use the GA 2 rack adapter (optional accessory). . For table top use, fix the plastic feet to the base of the unit. Note: Some furniture surfaces have been treated with varnish, polish or synthetics which might cause stains when they come into contact with other synthetics. Despite a thorough testing of the synthetics used by us, we cannot rule out the possibility of staining. Connecting the antennas . You can connect the following antenna types to the antenna inputs and : • two A 1031-U or A 2003-U passive antennas or • two A 12 active antennas or • a combination of passive antenna (A 1031-U or A 2003-U) and antenna booster (AB 2). Connecting the receivers You can connect up to four rack-mount receivers (e.g. EM 100 G2, EM 300 G2 or EM 500 G2) to the ASP 2. The splitter incorporates DC distribution for powering the receivers. . Pass the cables coming from the antenna spitter’s DC outputs through the cable grips at the rear of the receivers. . Insert the hollow jack plugs into the sockets of the receivers. . Connect the BNC cables and of the antenna splitter to the receivers as follows: • Antenna outputs (OUT A) to antenna inputs (ANT I) ! Antenna outputs (OUT B) to antenna inputs (ANT II) EM 500 G2 Note! . We recommend protecting unused RF outputs with a 50 . terminator in order to keep to the specified distribution attenuation. ASP 2 ASP 2 ASP 2 EM 500 G2 Connecting the mains unit The NT 1 mains unit can power up to four receivers. The DC power is also available at the antenna inputs for powering two optional antenna boosters. . Pass the cable through the cable grip . ASP 2 . Insert the DC connector on the power supply cable into the DC input . Note: The antenna splitter has no power switch. If problems occur... Error checklist Problem Possible cause Possible solution Receivers cannot be switched on Receivers are not powered Check the connections of the mains unit or the DC connections Disturbed reception or no reception Transmitting antennas are not within the range of the receiving antennas Reduce the distance between transmitter and receiving antennas Transmitters or receivers are not switched on Switch the transmitters or receivers on Antennas are not connected correctly Check the antenna connections Connecting cables are defective Replace the connecting cables Too high cable attenuation due to too long antenna cables or wrong type of antenna cable Only use the recommended antenna cables (see ”Accessories“ on page 21) or use shorter antenna cables Transmitters and receivers are not on the same frequency See operating manual of the transmitter or receiver If problems occur that are not listed above or if the problems cannot be solved with the proposed solutions, please contact your local Sennheiser agent for assistance.
